Knowledge Universe turns hard-to-visualize concepts into hands-on interactive laboratories. Explore animated equipment, rotate 3D models, change operating conditions, and discover how systems respond.
From transformers and marine engines to neural networks, quantum physics, and financial systems, learn what happens, why it happens, and how the underlying principles connect to the real world.
WHAT’S INSIDE
Explore 100+ categories across four universes, with more than 590 interactive labs available in this version.
• Engineering — power systems, substations, transformers, circuit breakers, HVAC, industrial automation, motors and drives, pumps, structures, renewable energy, batteries, robotics, marine engineering, and more.
• AI & Computing — neural networks and transformers, LLM fundamentals, prompts and context, retrieval, AI agents, computer vision, GPUs, data centers, cybersecurity, and cloud computing.
• Science & Mathematics — physics, chemistry, biology, quantum concepts, relativity, optics, waves, astronomy, orbital mechanics, statistics, vectors, and calculus.
• Business & Finance — accounting, corporate and personal finance, investing, banking, economics, entrepreneurship, marketing, operations, supply chains, and project management.
LEARN THROUGH INTERACTION
Operate equipment and explore concepts through topic-specific scenes, animations, diagrams, and experiments.
• Follow electrical power through substations, transformers, and protection systems.
• Trace airflow, refrigeration, fluid flow, and industrial processes.
• Explore engine strokes, rotating machinery, propulsion, and steering.
• Change loads, operating conditions, and control settings.
• Observe faults, overloads, flooding, and other abnormal conditions where supported.
• Explore mathematical surfaces, scientific relationships, and computational processes.
Animation helps reveal movement, flow, switching, sequencing, and cause and effect. Controls let you compare different conditions and connect what you see with the measurements.
UNDERSTAND THE MECHANISM AND THE MATH
Learning tools vary by lab and include:
• Tappable components with explanations and anchored labels.
• Cutaways, camera controls, and selectable reference diagrams.
• Live measurements, graphs, calculations, and event logs.
• Guided experiments with expected observations.
• Knowledge checks and troubleshooting activities.
• How It Works explanations, formulas, and worked examples.
• Stated assumptions and model limitations.
REFERENCE ILLUSTRATIONS
Explore reference drawings and formula sheets alongside the labs, including single-line diagrams, wiring schematics, process diagrams, comparisons, and calculation examples.

WHO IT’S FOR
• Engineering, science, mathematics, computing, and business students.
• Technicians and professionals reviewing underlying concepts.
• Educators looking for visual explanations and interactive demonstrations.
• Curious learners who want to understand how systems work.
The simulations are educational models with stated assumptions and simplifications. They support learning and exploration rather than replacing professional design, analysis, or equipment instructions.
New labs and learning resources are added regularly.
